[chromium] Reset the device scale factor to 1 before each test is run

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Terry Anderson]

Tests using testRunner.setBackingScaleFactor change the device scale factor but do not reset this back to 1 at the end of the test. This leads to a large number of flaky tests as noted in https://bugs.webkit.org/show_bug.cgi?id=83635

You should leave this line with the NOBODY (OOPS)! string.  The tools will fill it in based on who actually reviews the patch.

Nit:  "Unless required in order to force floating point math, do not append .0, .f and .0f to floating point literals."
